Hello everyone who reads this, I decided to tell you about my creation. This is a tank which consists of: Mindstorms NXT V1, but I decided to put V2.0, and the battery pack, 4 small motor and two receivers, then you will understand everything here are some pictures:

Now a closer look at the structure of the tower, as you can see I have collected two guns, how they work later I'll write here, but we are interested in how the details can not fly: a very simple

then the image shows a small engine (right) and gear (left)

how to build this gear is shown here:

I will slowly disassemble the turret of the tank and you'll see how it is arranged:

Excuse me for what I showed in the analysis of housing, but I can say that the engines are connected directly to the "gears" and here are some pictures
